The SPH10 provides superior analog telephone integration into
broadcast applications. The SPH10 also provides easy on/off control as
well as level adjustment of the Monitor Out jack from the front panel.
Front-Panel Controls
The SPH10 front-panel controls perform the following functions:
1. Send In. This trim pot adjusts the level of audio sent to the phone
line via the Send In jack. At its midpoint (6 o’clock position), the trim
pot is set for nominal send level (0dBm).
2. Aux Send. This trim pot adjusts the level of the auxiliary send audio
coming from the remote connector input and going onto the
telephone line to the caller. At its midpoint (6 o’clock position), the
trim pot is set for nominal level (0dBm).
3. Aux Out. This trim pot adjusts the level of the audio at the Aux Out
jack which includes both the caller audio and the send audio. At its
midpoint (6 o’clock position), the trim pot is set for nominal level
(0dBm).
4. Caller Out. This trim pot adjusts the caller audio level to the user’s
e uipment. At its midpoint (6 o’clock position), the trim pot is set for
nominal caller level (0dBm).
5. DIP Switches. Three active dip switches (2, 3, and 4) configure
the SPH10 system. Individual switch functions are defined in
Calibration (page 17).
6. Volume. These up/down buttons control the audio level of the
Monitor Out speaker amplifier. Pressing once changes the level by
1dB. Pressing and holding the buttons sweeps the level up or down.
7. On LED. This LED indicates the SPH10 has connected with the
telephone line. The LED illuminates green when the hybrid is on and
flashes green when the phone line is ringing.
